HEATING DRUM OR RADIATOR.

SPECIFICATION formingpart of Letters Patent No. 394,899, dated December18, 1888.

Application filed June 4, 1888. Serial No. 275,932. (No model.)

To all whom it may concern:

Be it known that I, ANSON \VOLCOTT, of Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Heating Drums or Radiators; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referenceniarked thereon, which form a part of this specification.

This invention relates to improvements in heating drums or radiators ofthat kind consisting of an exterior shell or casing, through which passthe smoke and heated products of combustion from a stove, furnace, orother heating apparatus, and which is provided with a plurality ofhorizontal or nearly-horizontal diaphragms or partitions forming atortuous pass ge for the flames and products of combustion leading fromthe inlet to the exitopening of the drum.

' The invention consists in the matters hereinat'ter (lescriliied, andpointed out in the ap pended claims.

In the accompanying drawings illustrating my invention, Figure 1 is aperspective view of aheating-drum embodying the same. Fig.

2 is a central longitudinal vertical sect-ion of i the same. Fig. 3 is asectional plan view of the same taken upon line 3 3 of Fig. 9.

In the accompanying drawings, Figs. 1, 2, and 3, A indicates as a wholethe external casing of the drum or radiator, which consists, in theinstance shown in the drawings, of two parallel side walls, A A, twoparallel end walls, A A a top wall, a, and a bottom wall, a.

B is an inlet-pipe leading from the smokeexit aperture of a stove,furnace, or otherheatin g device in which fuel is burned, or which mayconnect with an apparatus employed for the especial purpose of supplyingheated products of combustion, gases, or air to the radiator, or with aduct supplying live or exhaust steam.

C is an exit-pipe leading from the heatingdrum to a smoke-stack,chimney, or other exit-duct. The inlet-pipe B is connected with andopens into the bottom of the heatingdrum, and the pipe 0 opens out ofthe top thereof, the said pipe B in the particular c011- struction shownbeing connected with the topv plate, a.

I) I) D indicate a series of horizontallyarranged pipes or tubesextendii'ig transversely through the drum and connected at theiropposite ends with the side walls, A A, thereof. The said several tubesare arranged in several different groups or rows, D D D each rowconsisting of a plurality of pipes located side by side and near eachother. Between the rows of pipes are located one or more plates,partitions, or diaphragms, .E E E forming a tortuous passage leadingfrom the inlet to the outlet opening of the drum, and within which thesaid pipes are located. The several groups or rows of pipes in theparticular drum illustrated are arranged horizontally and one aboveanother, and the plates E E E are also horizontal, and said platesterminate short of the front and rear walls of said front and rearwalls. The several tubes or pipes D D I) open at their ends through theside walls, A A, and are secured in said side walls by having their endsinserted through and secured in circular apertures in the walls. Theplates E E E may be secured in any suitable or preferred manner to thewalls of the drum; but, as herein shown, they are provided with upturnedflanges riveted to the side walls, A A, and end wall, A ,i11 the mannerclearly illustrated in the drawings.

In the operation of the drum made as above set forth the heated productsof combustioi'i gases, air,or steamentering the inlet-openingot the drumflow through the tortuous interior passage thereof formed by the platesor diaphragms E E E and in so doing come in contact with and circulatearound the several air-pipes. The air within said pipes is thus heated,and, passing from the ends of the same, escapes into the room. The saidair-pipes thus afford a large additioi'ial heating or radiating surface,enabling a large proportion of the heat to be extracted from the air,gases, or steam passing through the drum or radiator.

The inlet-pipe B and exit-pipe C are located at that end of the drum atwhich the dia phragms E and are joined to the end Too wall, A and theparts of said diaphragms E l passing through the drum are made otherwiseand E iltljZlCQllh to said end wall are formed by valves or dampers F Ithe opening of which allows the smoke and products of combustion to passdirectly from the inlet-pipe B to the exit-pipe 0, thereby alibi-(ling aminimum amount of heating etteet from the drum. The said dampers F and Fare shown as pivoted at the adjacent margins of the diaphragms E E andas provided with. handles ff, extending through the side walls of thedrum for turning said dampers. By leaving closed one of said valves ordampers and opening the other the smoke and products of combustion maybe sent; through a partonly of the drum, thereby enz'ibling the quantityof heat given out to be conveniently regulated.

l closed, so that the smoke and products of combustion pass around oneset, I)", only of the air-heating pipes. By closing the damper F andopening the damper l?" the smoke and products of combustion will()lIH'lOLlSly pass around the diaphragm E, and will thus be brought intocontact with the two groups or rows I) D of the air-pipes.

\Vhen the. dampers F and h" are open, they rest in contact: with or nearthe ends of the intermediate diaphragm above them, or the top of thedrum in the case of the damper at tached to the uppermost diaphragm,thereby preventing the passage of the products of combustion through thesmoke-passage around the diaphragms, the ends of which smokepassages arethus closed by the said dampers.

It will of course be understood that the heating-drum embodying myinvention may have a greater or less number of rows of airpipes anddiaphragms than shown, and that a greater or less number of valves ordamp ers may be used, eorres 'londing with the number of diaphragms.'lhe air-pipes are not of course essential to the carrying out of myinvention; but their use is preferred, inasmuch as they add greatly tothe heating capacity of the drum.

The main feature of my invention, as t'aras the employment of valves forregulating the heat is concerned, may be carried out when the diaphragmsor partitions for giving tortuous course to the products of cmnlmstionIn Figs. 2 and 3, for instance, the damper F is shown as open and thedamper than in the manner shown, and my invent-ion is not thereforelimited to any 'iarticular construction in, the diaphragms themselves.

As a further improvement in heating-drums of the character set fortlnlprovide i 11 one of the end walls thereof a sliding door, H, extendingfrom the top to the bottom of the drum, and adapted to be drawn out oropened for the purpose of cleaning or removing soot from the interior ofthe drum. The door is made to extend to the bottom wall, a, of the drum,in order that soot or other substances accumulated upon the said bottomwall may be readily removed through the opening. As herein shown, thedoor or slide H consists of a Hat piece of sheet metal fitted at itsside edges in grooves 71 71. in the margins of the end wall, A The saiddoor H is shown as having its upper edge turned over a wire to form aledge or flange by which said door may be grasped in opening it.

I claim as my invention 1. In a heating-dru1n comprising an exteriorshell having oppositely-arranged in let and outlet openings and aplurality of parallel horizontal partitions or diaphragms forming atortuous passage leading from said inlet to the outlet opening, one ormore valves or dampers hinged to the ends of the z'tlterl'latepartitions or diaphragms in alignmtmt with said inlet and outletopenings and arranged to close the passages between said diaphragms,substantially as described.

2. The combination, with a heating-drum \Yitnesses:
